LEAF HOLDER.

Application filed January 19, 1928. Serial No. 247,904.

rlhis invention relates to improvements in leaf holders.

It is one of the objects of this invention to provide a leaf holder' foruse upon books, note-- books, and the like, which will maintain thepages .in position while the bool; is being used.

lt is a further object of this invention to provide a leaf holder whichwill serve as a book-marit, automatically keeping the proper place asthe pages are turned.

It is a further object of this` invention to provide a leaf holder whichconstructed of :i single length of wire without the use of any platemember or other means commonly employed for strengthening the clip.

It is a further object of this invention to provide alcaf holder whichvery simple in construction, is inexpensive, and is well adapted for thepurpose described.

lWith the above and other objects in view, the invention consists of theimproved leaf holder and all its parts and combinations as set forth inthe claims and all equivalents.

ln the accompanying drawing, in which the same reference charac-tersdesignate the same parts in allof the views:

Fig. l is a plan view of an open book with both left and right hand leafholders in attachment therewith, part of the book being' broken away;

F ig. 2 is a sectional view on the lino 2-2 of liig. l, the book boingclosed, and onlyT one leaf holder being shown and Fig. 3 is a front viewof a closed hook with one of the leaf holders in attachment therewith,part of the book being broken away.

Fig. 4 is an elevation of part of the device on a larger scale withparts in section to disclose the interconnection of the parts.

Referring to the drawing, the nume al 5 designates a book to which isattached the improved leaf holder. The latter comprises a single lengthof wire bent to form a finger' 6, a loop 7, a thumb projection 8, an arm9, a coil spring l0, a brace ll, and a clip member l2. The thumbprojection 8 is but a very slight bend at the end of the loop 7 toenable the iin ger 6 to be raised up when it is desired to i11- sert aleaf.

The brace 1l is a very important part of the device as it receives allof the strain caused by the tightening of the spring l() when the finger 6 is raised. As the brace bears against the cover of the book, thelinger can be raised without affecting the clip portion 12. Without thisbrace the strain would be imparted to the clip and it would be 4raisedup and caused to separate from the cover upon every manipulation of thefinger 6. ln other types of leaf holders, plates have been used eitheras the entire clip member or to strengthen a Wire clip to hold it inproper engagement. In this inf vention, the use of thebrace tostrengthen the clip eliminates the necessity of having a plate or otherseparate part, and thus simplifiesthe leaf holder by permitting it tobeconstructed entirely of a single length of wire.

A fur ther novel feature of this invention resides in the fact that thecoil spring lits outside of the leaves on the edges thereof, as shown inFig. 2, thus eliminating' the projection caused in many devices when thespring is positioned underneath the leaves.

l'n using the device two leaf holders may be employed as shown in Fig.l, one constructed for the left hand cover and one for the right, or asingle holder may be used. The device for the right hand cover acts asan automatic book-mark, for as the leaves are withdrawn and turned, itautomatically engages the next leaf. If the book is closed, it will markthe place where the user left off. The holders .for

both covers are designed to hold the pages iny place to prevent theirturning of their own accordor because of a breeze. lfVhen a device forthe left hand cover is employed, as a page is turned it is merelynecessary to engage the projection 8 with the thumb or finger, and raisethe finger 6 to insert the leaf, or to slip the leaf under the fingerwithout raising the hitter.

From the foregoing description it may be seen that the improved leafholder is simple in construction, is inexpensive to manufacture, and iswell adapted for the purpose described.

'What I claim is:

l. A leaf holder comprising a clip portion, a spring in connection withsaid clip portion, a brace member in connection with said sprinfr andextending within the clip portion, antv an arm joining said spring andextending in an opposite direction from the brace member.

2. A leaf holder comprising a clip portion, a spring in connection withsaid clip portion, a loop-shaped brace member in connection with saidspringend extending Within the clip portion, andan arm joining saidspring and extending in an opposite direct-ion from the brace member. ji

3. A leaf holder comprising a wire clip portion having two U-shapedsides, a spring in connection with an upper end portion of said clip, abrace in Connection with said spring and extending between the two Sidesof the clip, and an arm joining said spring and extending in an oppositedirection from the brace member.

4. A leaf holder comprising a wire clip portion having two U-shapedSides, a small coil spring in connection with an upper end oi Said clip,a loop-shaped brace ineinber in connection with said spring andextending between the two sides o" the clip, an arni joining said Springand extending in an opposite direction 'frein the brace member, saidarin having an upwardly bent end portion, and a linger extendingdownwardly 'from said arni.

5. A leali holder consisting of a single length of wire bent to Ylorin aclip portion, a

spring at an upper end ott said clip portion, a loop extending 'from thespring within the clip portion, and an arin ex'teijiding troin thespring in an opposite direction roin the loop.

6. A leaf holder consisting of a single length oi2 lwire bent to i'orina clip portion having two U-shaped sides, a coil Spring at an upper endof said clip portion,m a loopehaped brace extending from the springbetween the sides of the clip, an arni extending iiroin the spring in anopposite direction fron) the brace, a slight upward projection at theend ol .eaid a rin, and a linger extending downiardly from the a rin.

T. A leaA holder consisting olf a single length or' wire bent to iforina clip portion having two U-shaped sides, a small coil spring at anupper end of Said clip, the iree end of the clip portion being withinthe coil spring, a loop-Shaped brace ineinber extending frein the springbetween the sides oif the clip, an arin extending frein the spring in adirection oppeeite iti-oni the brace, a Slight upward projection at theend ol said arin, and a linger extending downwardly frein the arin.

ik leal holder consisting ot a single length oi? Wire bent to 'forni aclip portion, a epi-ing in connection with said clip portion, o baeeineinber extending from the Spring and an arin extending 'l'roin theSpring.
